The expansion of building blocks at the expense of agricultural land is one of the main problems causing climate change within the urban area of a city. The research came to determine these indicators, as a study was conducted on the expansion of the building blocks in three municipalities in the city of Baghdad for a period of four decades extended in the form of time cycles for the period (1981-2021) and using ArcMap GIS 10.7 technology. Then, the impact of this expansion on temperature rates was evaluated, as they are the most important climatic elements due to their significant effect on the rest of the elements. The results showed a clear, direct relationship between the increase in urban expansion rates and the corresponding rise i
... Show MoreIn this study, one-dimensional non-linear Klein-Gordon equations are solved by applying the integral transform known as the Rohit transform method. The approximate solutions of one-dimensional non-linear Klein- Gordon equations are obtained by combining the Adomian polynomials with the Rohit transform. To show the effectiveness and performance of the Rohit transform method, five one-dimensional non-linear Klein- Gordon type equations are considered and solved. The graphs of the solutions obtained are plotted to indicate the generality and clarity of the proposed method. It can be easily verified that the proposed method yielded the results that satisfy their corresponding non-linear Klein-Gordon equations. The integral Rohit transform co

Background: Urany1 acetate (UA) mostly a kidney poison or chemical toxic and not nearly so much radiological also is not accumulative toxic, so it is not concentrated in the food chain nor would it cause pathological condition due to increase levels from expomers. Therefore, the study aimed to detect the target organ as most of the lethal dose (LD50) male rats died within 24 hours.
Methods: Study was done on (120) male rats of 2 months old, at varying dosage level of uranyl acetate ranging from LD 50 of 2.5 and 1.5gm/kg and varying dosage level, by oral intubation. There were (40) rats for LD 50 were given single oral dose from 2.5 to 1.5 gm /kg every day. Eighty rats for the main study, (20) rats each gr
In this research, the dynamics of double-head streamer discharge initiation, propagation, interaction and breakdown in the air under different pressure values were presented. The double-head streamer discharge dynamics were analysed within a plane-to-plane electrode configuration. That was done through many aspects proposed, such as electron density, electric field, space charge density and streamer propagation speed. The simulation performed using ‘COMSOL Multiphysics’ is based on the finite element method and was carried out with the fluid model. The fluid model describes the movement of particle concentrations using partial differential equations (PDEs) together with Poisson’s equation; Poisson's equati

Many face recognition algorithms have been proposed thus far; however, achieving high recognition accuracy and low execution time remains a challenge. In this work, a new scheme for face recognition is presented using hybrid orthogonal polynomials to extract features. The embedded image kernel technique is used to decrease the complexity of feature extraction, then a support vector machine is adopted to classify these features. Moreover, a fast-overlapping block processing algorithm for feature extraction is used to reduce the computation time. Extensive evaluation of the proposed method was carried out on two different face ima

Background: The development of non steroidal anti-inflammatory drugs (NSAIDs) was based principally on inhibiting cyclooxygenases (COX) activity. However, the identification of two
COX- isoforms (i.e., COX-1 and COX-2) with different physiological effects has led to the development of COX-2 specific NSAIDs, with fewer adverse effects than traditional NSAIDs.
Therefore, They are expected to produce anti-inflammatory activity with minimal adverse effects on GI mucosa, as well as, other structures and cells such as platelets.
The aim of this study is to evaluate the effect of selectivity of COX-2 inhibitors on many organs and systems function such as the hepatobiliary system, platelets function, as well as, seru
